I've been watching this over and over each year since the 80's. The refs wont change. The players need to adapt. And yes, the coach too.
LeBron needs to learn how to "sell" fouls like Harden does. He gets whacked every single drive, and instead of "taking it like a man" he needs to pressure the refs by flopping, shouting, or whatever. No need for and-1's. Make the no-call a non-possibility.
JR needs to learn to elbow down low, not in the face, and in general be more cool. Suspensions for starters are simply not worth it.
David needs to find the right moment for a T. Needs to draw the line for the guys, the refs, the crowd, and the media. When a guy injures your player on purpose and doesn't get ejected, or at least a T, and you don't "flip out" - you're sending the message that it's ok. And he saw it clearly.
What Perkins did to Crowder is how you win in the playoffs. You hit back harder.
Iman was extraordinary BTW. The game could've easily gone the other way if not for him.
